GATE.

SPECIFICATION forming part of Letters Patent No. 781,235, dated January 31, 1905. Application filed May 2'7, 1904. Serial No. 210,083.

To all whom it may concern:

Beit known that I, GEORGE W. SITES, a citizen of the United. States of America, residing at Lyons, in the county of Boulder and State of Colorado, have invented certain new and useful Improvements in Gates; and I do declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in gates of the class usually termed farm-gates and'also of the class provided with chains,

cords, or cables which may be used to open and close the gate, as may be desired. In this class of apparatus the manipulating parts extend from the gate a suificient distance on.

each side to enable the driverof a vehicle to operate the gate from his position therein.

My improvedapparatus consists of certain novel features of construction, all of which will hereinafter be described 'in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof. In the drawings, Figure 1 is a side view of my improved gate mechanism, the operating cords, ropes, or cables being broken for lack of space on the sheet. Fig. 2 is a view of the gate, taken at right angles to Fig. I. This may be called a section taken on the line 2 2, Fig. 1, with a slight change in the scale of the drawing so far as the elevation or height of the gate is concerned. Fig. 3 is atop view of one of the posts, showing its laterally-extending arm.provided with a guide-pulley. Fig. i is a detail view of the pulley over which the rope or cable connected with the gate passes, shown on a larger scale. In this view the top bar mounted on the posts forming the vertical guides for the gate is shown, also the depending guide-pulleys. Fig. 5 is a section taken on the line 5 5, Fig. 4c, viewed in the direction of the arrow. Fig. 6 is a diagrammatic view illustrating the cables and the location of the various pulleys.

The same reference characters indicate the sameparts in all the views.

Let A designate each of two vertical posts connected at the top by a beam A. These posts form vertical guides for the gate B, which is provided with metal parts B at its extremities, the said parts being adapted to straddle the posts A on the inside, thus holding the gate in place during its operation. To the top central part of the gate is attached an eye B with which is connected one extremity of a cable B which passes over sheaves B and B mounted on the beam A. is mounted on the beam near its center, while the sheaf B is mounted on theextremity A of the beam, which projects beyond one of the posts A. To the extremity of the cable B remote from-the gate is attached a weight B, preferably of sufficient gravityto balance the gate or approximately balance the latter.

Mounted on Opposite sides of the posts A and, at the same distance from the gate are eral arm O, having a sheave-holder C, carrying a sheave C The cross-beam A is also provided with sheaves O C, and C, mounted in holders O O and U suitably connected with the beam. The sheaves C 0*, and C are located adjacent the sheave B, but project below the beam instead of above the same."

An'endless operating-cable D is employed. This cable is indicatedby the light dotted lines in Fig. 6, while the cable B connected with the gate, is indicated by the heavy dotted lines in this view. The cable I) passes around the sheaves or pulleys (J on opposite sides of the gate and also engages the sheaves C C, C,

of the arrow at, the cable passes under the pulley C thence up over the pulley B, thence down under the pulley C, thence around the pulley C farther to the left, thence over the pulley C and thence around the-pulley O farther to the right. The cable is proividedon each side of the gate with a depending handle E, connected with the gate by a suitable flexible device E. The user of the gate may open thelat- I ter by using either one of these handles and posts C, each of which is provided with a lat- The sheaf B and B. Following the cable D in Fig. 6 from I the sheave (l at the right and in the direction may close the gate after he passes through the gate-opening by the use of the other handle. Again referring to Fig. 6, if the handle E on the left of the gate or at the left of the figure is moved from the full-line position 1 to the dotted-line position 2 the gate will be opened, since the operating-cable D will be moved the distance between the positions 1 and 2, and this movement of the cable will turn the sheave B sufliciently to raise the gate. It is also evident that if the gate be approached from the right (referring to Fig. 6) the gate may be opened by moving the handle E at the right from the position 3 to the position 4. Now if it be assumed that the user of the gate is approaching from the left of Fig. 6 or going in the di rection indicated by arrow K he grasps the handle E and moves it from the position 1 to the position 2. This opens the gate, and he drives through. After passing through the gate he grasps the handle E on the opposite side and moves it from the position 4: to the position 3 or in the reverse direction from the opening movement of the operating cable. This movement of the handle E from the position t to the position 3 moves the cable the same distance as the opening movement thereof in the reverse direction. Hence this movement of the handle E from 4 to 3 will operate the sheave B sufficiently to close the gate. It

will be observed that the cable 1) and the ca ble B both pass over the pulley B".

Having thus described my invention, what I claim is 1. The combination with a suitable frame and a gate vertically movable thereon, of a cable connected with the gate, sheaves mounted on the frame over which the cable passes, a counterbalance-weight connected with the cable, an endless operating-cable extending from the gate in opposite directions, and suitable guide-sheaves engaged by the endless cable which also engages one of the sheaves over which the cable connected with the gate passes whereby as the endless cable is actuated, the

. sheave over which the gate-cable passes is actuated to raise or lower the gate, substantially as described.

2. In a gate and operating means, the combination of a suitable upright frame, a gate vertically movableon the frame, a cable connected with the gate, sheaves mounted on the frame above the gate over which the gatecable passes, a counterbalance weight connected with the gate-cable, guide-pulleys also mounted on the frame above the gate, posts located at a suitable distance from the gate on opposite sides, pulleys supported by the posts, and an endless operating-cable engaging all the pulleys and one of the sheaves engaged by the gate-cable, whereby as the endless eable is actuated the gate is operated, substantially as described.

3. The combination with a suitable upright frame, of a gate vertically movable on said frame, a cable connected with the gate at one extremity, a counterbalance-Weight connected with the cable at its opposite extremity, sheaves mounted on the frame over which the said cable passes, three depending guide pulleys mounted on the frame above the gate, posts located on opposite sides of the gate, guidepulleys mounted on the posts, and an endless operating-cable engaging the guide-pulleys and also one of the sheaves engaged by the gate-supporting cable whereby as the operating-cable is actuated the gate is operated as set forth.

4:- The eombination with two posts suitably separated, a beam connecting the posts at the top, a cable vertically movable on said posts, a cable connected with the gate, sheaves mounted on the beam connecting the posts, the gatecable passing over said sheaves, a weight connected with the cable, guide-pulleys suitably supported above the gate and on op posite sides thereof, an endless operating-cable engaging the guide-pulleys and passing over one of the sheaves engaged by the gate-supporting cable, and handles connected with the operating-cable for the purpose set forth.

5. The combination of a suitable frame, a gate vertically movable thereon, a flexible device connected with the gate, a sheave mounted on the frame and over which the flexible device passes, a counterbalance-weight connected with the extremity of the flexible device remote from the gate, guide pulleys mounted on the frame and other guide-pulleys, suitably supported on opposite sides of the gate, and an endless flexible operating device engaging these guide-pulleys and also engaging the sheave which is engaged by the flexible device connected with the gate whereby as the flexible operating device is actuated the gate is operated, substantially as described.
